How Exothermic Welding Works ?

The Exothermic weld System is a welding process that utilizes an exothermic reaction (a chemical reaction that releases energy in the form of very high temperatures and light) to permanently joins metal connections. Exothermic weld uses a light-weight, clamp-on graphite mold to safely position and contains any weld required. The exothermic reaction creates an intense miniature furnace with temperatures exceeding 2,500 °F, instantly producing molten metal which flows into the weld cavity, filling any available space. After waiting adequate time after the initial process, the mold can be released and the finished connection removed.

When Exothermic Welding is require ?

When there is an improper connections between conductors which are often the reason for electrical malfunctions. A proper connection should have the following characteristics:

3. Connector temperature should remain lower than that of the conductor when conducting electrical current.

4. Extensive service life. Will not deteriorate, corrode or decay over time, above or below-grade.

Only exothermic weld connections meet or exceed all of the above criteria. Exothermic weld is recommended by IEEE and IEC. It has been shown to be the best choice where safety, reliability, longevity and current carrying capacity are critical. Exothermic weld specifically supersedes its competition with its hermetically sealed metallized pouch which provides the product with an extensive shelf life and easy portability. Our AmiableWeld Exothermic Welding Powder is ISO Certified, CE and ROHS Compliance and IEEE Tested and Passed and is the preferred method for making copper-to-copper and copper-to-steel electrical connections.

Exothermic welding is also sold in the Market in names such as AMIABLEWELD, CAD WELDING, CAD WELD.

Exothermic Weld Process :

The process of Exothermic Welding is a method of making electrical connections of copper to copper or copper to steel in which no outside source of heat or power is required. In this process, a special Welding material is placed into a high temperature resistant mold and ignited.

The process of igniting the particles creates extremely high heat and molten metal (exothermic reaction) more than 2000 degree Celsius, and produces a molten metal slag. This liquid copper metal flows into the Welding cavity, filling any available space and completes the Welding. The Welding is then allowed to cool and solidify before it is removed from the mold. The mold is ready for the next Welding after a brief cleaning with a brush. This entire process takes only seconds to complete.

Exothermic Welding connections produce a permanent connection, superior in performance to any known mechanical or pressure type surface-to-surface contact connector. Because the connection produced is a molecular bond, an exothermic Welding connection will not loosen or increase in resistance over the lifetime of the installation.

Exothermic welding process is different of different companies who sells in their own Brand name as AMIABLEWELD, CADWELD.

Advantages of using Exothermic Welding:

1. It guarantees the most common connections not only between copper cables but also for Welding tapes and metallic pieces made of brass, stainless steel, and copper coated steel earth rods. Current carrying (fusing) capacity equal to or greater than the conductor.

2. It offers a permanent Welding and a low resistance connection, essential for achieving longwearing and trustworthy results in earthing.

3. It does not corrode oxide or degrade with time and is resistant to galvanic coupling.

4. It has higher mechanical and squeezing resistance than the conductors themselves.

5. It has a superior electrical conductivity than the conductors themselves.

6. Permanent molecular bond that will not loosen or corrode.

7. It is able to withstand repeated electrical discharges.

8. No external power or heat required.

9. Can be checked visually for quality.

10. It never increases its resistance.

11. Will withstand repeated faults.

12. Will not deteriorate with age.

13. No special skills required.

14. Easily transportable.

15. Low labor costs.

Exothermic weld system from AmiableWeld provides precision engineered molds for optimal results which gives about 30 to 100 Joints from one Graphite Mold. Features include simplicity, corrosion resistance, extended shelf life, high conductivity, portability, ease of use, and it requires no external heat or power source.

Exothermic welding is also supplied worldwide with Brand names such as AMIABLEWELD, CADWELD.

Why Use Exothermic Weld ?

The Exothermic Weld Connecting created a permanent, homogeneous, and molecular bond that cannot loosen or corrode, and will carry more current that the conductor.

The Exothermic Weld Connection are solid molecular bonds, they do not loosen or corrode over the lifetime of connection. The ame cannot be said about other methods; such as brazing, crimp, split bolt, or compreion type connections.

Exothermic welding is also procured worldwide with Brand names such as AMIABLEWELD, CAD WELDING.

Advantages and Disadvantages of Exothermic Weld:

Compared for some other forms of welding, exothermic bonds employ a greater mechanical toughness. The weld can be proof against corrosion. You simply won't notice an increase in electrical excess weight despite repeated small signal pulses; your weld is highly firm. The procedure is more costly, however. The task requires replaceable moulds but from One Mold can do approx 30 - 100 Joints.

Exothermic weld is usually used for welding copper conductors but is suitable for welding a wide range of metals, including stainless steel, cast iron, common steel, brass and bronze. It is especially useful for joining dissimilar metals.

An exothermic weld has higher mechanical strength than other forms of weld, and excellent corrosion resistance It is also highly stable when subject to repeated short-circuit pulses, and does not suffer from increased electrical resistance over the lifetime of the installation. However, the process is costly relative to other welding processes, requires a supply of replaceable moulds, suffers from a lack of repeatability, and can be impeded by wet conditions or bad weather.

Exothermic weld Kit is also Manufactured or procured and sold worldwide in Brand names such as AMIABLEWELD, CADWELD.
